How do I convert bushels to tons for wheat or corn?

Multiply bushels by the crop test weight per bushel, then divide by 2,000 for short tons. Wheat runs about 60 lb per bushel and corn about 56 lb, so 1,000 bushels of wheat is roughly 30 tons and the same corn count is 28 tons. Use the Bin Capacity and Mill Throughput calculators with your actual bulk density rather than book weight, since moisture and packing shift real density by several percent.

How much moisture shrink should I expect when milling or drying?

Shrink tracks the moisture you remove. Every point of moisture taken out of 1,000 lb of grain removes roughly 10 to 11 lb of water plus a small handling loss, so drying corn from 20 to 15 percent costs about 6 percent of shipped weight. The Moisture Loss calculator returns shrink in pounds and percent so you can reconcile intake scale tickets against finished tons and price the shrink into your Cost Per Ton.

How do I size a bucket elevator or auger to keep up with the mill?

Match capacity in tons per hour, not just bushels. Run the Mill Throughput calculator for your target rate, then use Elevator Capacity and Auger Rate to confirm the leg and screw exceed it with headroom, since handling gear rated at 100 percent of mill rate will bottleneck the moment intake surges. Auger rate falls sharply with incline and fullness, so derate a 45-degree screw well below its horizontal spec.

What blend accuracy do I need for medicated or micro-ingredient feed?

Micro and medicated ingredients typically require the finished blend to hold coefficient of variation at or below 10 percent, and many drug label claims demand tighter. The Batch Blend Accuracy and Ingredient Dosing Variance calculators convert scale tolerances and mixer performance into expected CV so you can prove uniformity before a run and flag when a mixer or scale needs recalibration to stay inside label tolerance.

How do I calculate cost per ton for milled or bagged product?

Roll raw material, energy, labor, packaging, and shrink into finished tons, not intake tons. Use Yield Loss and Moisture Loss to get true saleable output, Energy Per Ton for the kWh burden, and Bagging Labor plus Pallet Count for packaged product, then combine them in the Cost Per Ton calculator. Feeding that result into the Margin calculator gives a quote that survives an audit of your actual scale tickets.

How do I size dust collection load for a grinding or handling system?

Dust load scales with the airflow at each pickup point and the grain volume moving through it. The Dust Collection Load calculator estimates the CFM and dust mass the baghouse must handle across your transfer points so you can confirm the collector is not undersized, which matters for both NFPA combustible dust compliance and keeping fines out of finished product. Pair it with Sanitation Downtime when a filter change falls inside the run window.

Best calculators in this category

Mill Throughput: Calculate effective mill throughput for wheat, corn, soy, flour, meal, or feed production using milled output, runtime, and realistic operating efficiency.
Screen Change Impact: Estimate the throughput impact of a hammer mill, screener, or classifier screen change using post-change output, runtime, and expected efficiency.
Moisture Loss: Calculate moisture-related weight loss for grain, flour, meal, pellets, or dry ingredients by comparing moisture loss weight with the starting product weight.
Bin Capacity: Estimate usable bin, hopper, or silo capacity for grain, flour, feed, pellets, or dry ingredients using fill per loading cycle, loading cycles, uptime, and usable yield.
Dust Collection Load: Estimate dust collection load from milling, conveying, screening, or bagging by combining dust captured per collection cycle, available cycles, collector uptime, and capture yield.
Batch Blend Accuracy: Calculate batch blend accuracy margin by comparing actual ingredient addition against required formula weight and normalizing the difference to the batch reference weight.
Energy Per Ton: Estimate energy cost per ton for milling, conveying, grinding, pelleting, mixing, or bagging using connected load, runtime, energy rate, and processed tons.
Yield Loss: Calculate milling or feed production yield loss by comparing lost product weight with total input or production weight and a target loss rate.
Packaging Rate: Calculate packaging completion rate for bags, totes, supersacks, or bulk containers by comparing accepted packages with total planned packages and a target packout rate.
Cost Per Ton: Estimate dry bulk production cost exposure and cost per ton using processed tons, variable cost per ton, included cost share, and fixed run cost.
Grind-Size Test Throughput: Estimate the practical rate for completing grind-size distribution checks by comparing sample weight processed through sieves or particle-size testing with test runtime and lab efficiency.
Elevator Capacity: Estimate usable bucket elevator capacity for grain, feed, flour, pellets, or dry ingredients using tons per bucket cycle, available cycles, elevator uptime, and fill efficiency.
